Super cold fluid started leaking inside on drivers side of vehicle. on 1995 Plymouth Grand Voyager

While driving my vehicle last summer, I would have the A/C on. During these times extremely cold liquid would come pouring down over my feet (often in sandals - LOL) when making a turn. It happens numerous times on the drivers side and once or twice on the passenger side.
Now, my A/C only blows hot air. How can I find out and repair this problem without a major expense (limited income)? Is this easy to replace?
